Test the Digestibility of Fermented Shrimp Waste Flour with Serratia Marcescens Bacteria in Male Broilers Aged 6 Weeks

Introduction

The use of fermented shrimp waste flour as an alternative source of feed in broilers has gained significant attention in recent years. Shrimp flour is a side product that is rich in protein and nutrition, but is usually less utilized in animal feed. The fermentation process using bacteria such as serratia marcescens is expected to increase the digestibility and nutritional quality of shrimp waste flour. However, the optimal concentration and type of bacteria required for fermentation are still unclear. This study aims to evaluate the digestibility of fermented shrimp waste flour with various levels of serratia marcescens bacteria in male broilers aged 6 weeks.

Background

Shrimp waste flour is a by-product of the shrimp processing industry, which is rich in protein and other nutrients. However, its utilization in animal feed is limited due to its low digestibility. Fermentation using bacteria such as serratia marcescens is a potential method to increase the digestibility and nutritional quality of shrimp waste flour. Serratia marcescens is a type of bacteria that is commonly used in fermentation processes, and its ability to break down complex nutrients has been well-documented.

Methodology

This study was conducted at the Veterinary Biology Laboratory at the Department of Animal Husbandry, Faculty of Agriculture, University of North Sumatra. The study involved 20 male broilers with an initial weight of 1.79 ± 0.11 kg, which were divided into four treatment groups (R0, R1, R2, and R3). Each treatment group consisted of five replications, with one chicken per plot. The study used a Completely Randomized Design, which is a statistical method used to analyze the effects of different treatments on a response variable.

Results

The results of the study showed that the treatment of R0, R1, R2, and R3 in chickens did not show a significant difference (P> 0.05) against energy excretion, metabolic energy, and nitrogen retention. This suggests that the addition of serratia marcescens bacteria at different levels may not have an expected effect on feed digestibility.

Discussion

The results of this study provide an important insight into the use of fermented shrimp waste flour as an alternative source of feed in broilers. The fermentation process plays an important role in increasing the availability of nutrients, especially protein, which can affect the growth and health of chickens. However, the results that show the absence of significant differences in energy excretion and nitrogen retention obtained from various treatments show that the addition of the bacterial level may not have an expected effect on feed digestibility.

This raises questions about optimal concentrations and other types of bacteria that may be more effective in fermenting shrimp waste flour. Further research is needed to explore various factors, including a combination of different bacteria, fermentation time, and other processing methods to maximize digestibility and utilization of shrimp waste flour in chicken feed.

Conclusion

The results of this study can be the basis for applying the use of more efficient shrimp waste, which can not only reduce feed costs but also help in reducing waste from the fisheries industry. Livestock feed optimization through a more sustainable approach is also in line with global trends that support environmentally friendly and sustainable animal husbandry practices.

Recommendations

Based on the results of this study, the following recommendations can be made:

Further research is needed to explore various factors, including a combination of different bacteria, fermentation time, and other processing methods to maximize digestibility and utilization of shrimp waste flour in chicken feed.
The optimal concentration and type of bacteria required for fermentation should be investigated to determine the most effective method for increasing the digestibility and nutritional quality of shrimp waste flour.
The use of fermented shrimp waste flour as an alternative source of feed in broilers should be promoted as a sustainable and environmentally friendly approach to animal husbandry.

Future Directions

This study provides a foundation for further research on the use of fermented shrimp waste flour as an alternative source of feed in broilers. Future studies should focus on exploring various factors, including a combination of different bacteria, fermentation time, and other processing methods to maximize digestibility and utilization of shrimp waste flour in chicken feed. Additionally, the optimal concentration and type of bacteria required for fermentation should be investigated to determine the most effective method for increasing the digestibility and nutritional quality of shrimp waste flour.

Limitations

This study has several limitations, including:

The study was conducted with a small sample size, which may not be representative of the larger population.
The study only investigated the effects of serratia marcescens bacteria on feed digestibility, and did not explore other factors that may affect the nutritional quality of shrimp waste flour.
The study did not investigate the economic viability of using fermented shrimp waste flour as an alternative source of feed in broilers.

Conclusion

In conclusion, this study provides an important insight into the use of fermented shrimp waste flour as an alternative source of feed in broilers. The fermentation process plays an important role in increasing the availability of nutrients, especially protein, which can affect the growth and health of chickens. However, the results that show the absence of significant differences in energy excretion and nitrogen retention obtained from various treatments show that the addition of the bacterial level may not have an expected effect on feed digestibility. Further research is needed to explore various factors, including a combination of different bacteria, fermentation time, and other processing methods to maximize digestibility and utilization of shrimp waste flour in chicken feed.
